Referring more particularly tothe dra'wing, our Other modes of applying the principle of our electric switch in its illustrated embodimentl is invention may be employed instead of the one intended to be installed -at the juncture point of explained, change being made as regards the 55 vmechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention:

1. In a device of the class described, a housing, an electrical unit received therein, removable through one end thereof, a socket mernber of insulating material sec'uredffin the othe'rend of the housing, yprovided with a pair of openings sub stantially parallel to the axis of removal of said unit, and extending from thefinteriorr of the housingto .the exterior thereof, a pair of contactabrushes loosely received in said openings so as to be removable .therefrom as the` unit isremoved from the housing, and a plug for connect? ing a conductor to said unit, including a pair of contact prongs, detachably receivable in said openings in contact with said brushes. f

2. In a device of the class described, a housing, an electrical unit. received` therein, removable through one end thereof, a socketmember of insulating material secured in the other end of they housing, provided with a. pair offopenings substantially parallelzto the axis of removal of said unit, and extending from the interior of -the housing to the exterior thereof, a pair of ing, an electrical unit received-therein, removable through one end thereof, a socket member of insulating material secured inthe other end of the housing, provided with a pair of openings substantially parallel to the axis of removal of said unit, and extending from the interior of the ,housing to the exterior thereof, a pair of resilient contact brushes loosely received in said openings so as to be removable therefrom as the unit is removed from the housing, and a plug for connecting a conductor to-saidA unit, including a pair of contact prongs, detachably receivable in said openings in contact With said brushes.
